The HUE web server has DES and 3DES ciphers enabled on the web server.
A vulnerability validation has marked this as vulnerable and needs to be disabled.

Use the following steps to disable the DES and 3DES ciphers in the Hue web server configuration.
  1. Go to the Cloudera Manager UI and navigate to, Hue > Configuration > "Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini"
  2. Add the following property using the available ciphers (listed below) and include either "-DES:-3DES" (to remove the ciphers from the list) or to permanently remove them use, "!DES:!3DES"
    List of Ciphers
    For example, to permanently disable the DES and 3DES ciphers, the end of the cipher list would look like the following:
    For more information on the cipher list format and syntax see the following web page: https://www.openssl.org/docs/man1.0.2/apps/ciphers.html
